How can you set a plugin as paid

Once a plugin is marked as a premium plugin in prosites it is made available for activation by the sub site administrator.

My question is possible to set a plugin as pay-to-use? So instead of activating the plugin they are then redirected to a cart of some sorts to pay for the plugin

This plugin provides a custom link to direct the user to a location apart from linking to documentation how can one set a plugin be bought through this plugin as indicated in the overview video?
